The St Helens boxer challenges WBA middleweight champion Gennady Golovkin on Saturday night, but must upset the odds in Monte Carlo if he is to become the first person to defeat the Kazakh.
Golovkin has won all of his world title fights by stoppage and has not been taken the full 12 rounds in seven years.
However, Murray, who held WBA super champion Felix Sturm to a draw and floored Sergio Martinez before losing to the WBC champion on points, is focused only on victory.
???The weigh-in went great, I???ve done my work the best I???ve ever done it and I???m feeling good,??? Murray told Sky Sports News HQ.
???I???ve had a hard 12-week training camp and I???ve done everything possible and given myself every possible opportunity to win this fight.
Undefeated Golovkin has claimed 28 of his 31 wins inside the distance and has the highest knockout percentage of any current boxing champion.
???His record speaks for itself, but I???ve not been focusing on that, I???ve just been focusing on winning,??? added the St Helens boxer, 29-1-1 (KO 12).
???I???ve accepted that he punches hard, obviously with his record, and I???ve accepted that I???m going to go through a little bit of pain, well I say a little but maybe a lot.
???I???ve just accepted it and whatever it takes to win I???ll just get through it.
???To be honest with you, we???ve not just got one specific game plan, he???s not shown many chinks in his armour so we don???t know and we don???t have a lot to work on.
???But I???ve got a great trainer in Oliver Harrison and we???ve been working on some good tactics that we think are going to work, we???ve got that many different plans, so it just up to me now to go in there and make them work.???
